Dozens of Roman Catholic institutions in eight different states filed suit against the federal government today challenging the constitutionality of the requirement that employers provide birth control coverage to their employees. In this they joined by a private employer who filed a similar suit in a Missouri two months ago. The plaintiffs all contend that the the federal mandate violates their right to religious freedom. Furthermore, the Missouri legislature has reportedly enacted a statute authorizing employers not to cover contraception or sterilization services.
